Intravitreal Dexamethasone Implant in Crystalline Lens
Narrative Responses:
Purpose
To report a case of inadvertent injection of dexamethasone implant into the crystalline lens.
Methods
A 58-year-old man, developed macular edema due to the superior temporal vein occlusion in the right eye. Dexamethasone implant were injected inadvertently into the crystalline lens. Patient was followed one month after the injection. Macular thickness, intraocular pressure and lens status were evaluated.
Results
Before injection of the dexamethasone implant, his best corrected visual acuity was 20/200 and anterior segment examination showed early nuclear cataract. Macular edema was detected due to the superior retinal vein occlusion and central macular thickness was 495µ in the right eye. Intralenticular dexamethasone implant localization were clearly imaged by high-frequency ultrasound biomicroscopy using the HiScan system (Optikon 2000 SpA). Patient was followed without cataract surgery because no progression of cataract formation was detected during the follow up period. Best corrected visual acuity increased to 80/200 and macular thickness was decreased to 426µ one month after the injection.
Conclusion
In this case, we followed the patient without reposition of the dexamethasone implant because of not observing any side effect due to this situation. Despite this localization of the implant, visual acuity improved and macular thickness decreased.
